Mispronunciation Detection For Language Learning And Speech Recognition Adaptation, Zhenhao Ge
Mispronunciation Detection For Language Learning And Speech Recognition Adaptation, Zhenhao Ge
Open Access Dissertations
The areas of "mispronunciation detection" (or "accent detection" more specifically) within the speech recognition community are receiving increased attention now. Two application areas, namely language learning and speech recognition adaptation, are largely driving this research interest and are the focal points of this work.
There are a number of Computer Aided Language Learning (CALL) systems with Computer Aided Pronunciation Training (CAPT) techniques that have been developed. In this thesis, a new HMM-based text-dependent mispronunciation system is introduced using text Adaptive Frequency Cepstral Coefficients (AFCCs). It is shown that this system outperforms the conventional HMM method based on Mel Frequency Cepstral …
A Declarative Domain Independent Approach For Querying And Generating Visualizations, Nicholas Ricky Del Rio
A Declarative Domain Independent Approach For Querying And Generating Visualizations, Nicholas Ricky Del Rio
Open Access Theses & Dissertations
Constructing visualizations using modular visualization environments (MVEs) requires knowledge about visualization transformation theory as well as implementation specific details about how to programmatically chain together relevant sets of modules into pipe and filter-like architectures known as pipelines. Constructing visualization pipelines introduces a number of challenges including: understanding how to transform raw data into forms that can be ingested by MVEs, identifying target modules that map data into graphical data, and understanding how to further transform resulting graphical data into forms that can be presented. Users typically must immerse themselves in a deluge of documentation and usage examples before becoming proficient …
Applications Of Agent Based Approaches In Business: A Three Essay Dissertation, Shankar Prawesh
Applications Of Agent Based Approaches In Business: A Three Essay Dissertation, Shankar Prawesh
USF Tampa Graduate Theses and Dissertations
The goal of this dissertation is to investigate the enabling role that agent based simulation plays in business and policy. The aforementioned issue has been addressed in this dissertation through three distinct, but related essays. The first essay is a literature review of different research applications of agent based simulation in various business disciplines, such as finance, economics, information systems, management, marketing and accounting. Various agent based simulation tools to develop computational models are discussed. The second essay uses an agent-based simulation approach to study important properties of the widely used most popular news recommender systems (NRS). This essay highlights …
